Former secretaries of state Henry Kissinger and George Shultz called for an end to nuclear weapons a few years ago, but the movement failed to gain a foothold. So why do countries continue to spend billions of dollars to modernize and expand their nuclear arsenals? What would make nuclear disarmament possible? Ward Wilson joins us to talk about his book, "Five Myths About Nuclear Weapons."
